Definition:
Classification of a reflection so as to indicate its status with respect to inclusion in the refinement and the calculation of R factors.
Type: code
Mandatory item: no
Alias:Related item: _refln.status (alternate)
The data value must be one of the following:
|
o | (lower-case letter o for 'observed') satisfies _refine.ls_d_res_high satisfies _refine.ls_d_res_low exceeds _reflns.threshold_expression |
|
< | satisfies _refine.ls_d_res_high satisfies _refine.ls_d_res_low does not exceed _reflns.threshold_expression |
|
- | systematically absent reflection |
|
x | unreliable measurement -- not used |
|
h | does not satisfy _refine.ls_d_res_high |
|
l | does not satisfy _refine.ls_d_res_low |
